Last Updated:

This Reduced BOM schematic for the HX3 CYUSB331x family enables customers to design a low cost USB 3.0 hub that meets USB-IF certification requirements.

Optional features available in the CY4603 DVK (which demonstrates the CYUSB331x family) features such as External EEPROM, Port Status Indicator LEDs, Overvoltage Protection IC, Reset Button, Mode Select Jumper Blocks and Diodes for additional ESD/EMI protection have been excluded.

The features supported are:

  1. 4 Downstream (DS) USB 3.0 ports
  2. Supports Battery Charging v1.2 on all Downstream ports
  3. Supports Ghost Charging™
  4. Supports individual DS port power control - supplies current up to 2.1A per Downstream port

The Reduced BOM design continues to support HX3 configuration through the Blaster Plus utility , when used with either an external EEPROM or an I 2 C Master.
